APPARATUS FOR SUPPLYING HOT WATER IN HOUSES.

Specification of Letters Patent.

Patented May 1d, 1921.

To all whom it may concern:

'Be it known that we, JOSEPH T. MANNING and CHARLES 1F. CLUDIUs, both of us citizens of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Apparatus for Supplying Hot Water in Houses, of which the following is a specification.

This invention relates to apparatus whereby water which has been heated and then filtered in heated condition can be withdrawn in heated condition promptly upon opening any faucet on a pipe line leading thereto from the filtering appliances.

Heretofore in probably the majority of houses having water systems the apparatus has been such that the water in the hot water pipe line cools ofi unless one or more open faucets are causing a flow; and hence upon opening a faucet after all faucets have been closed for a considerable time the cooled water must beallowed to run out and the pipe line to fill again before hot:water will appear at the faucet. In many houses, however, in order'to ayoid this defect, the hot water pipe line has been connected with the hot water storage tank (if one should be used) or with the hot water heater (if a hot water storage tank shouldnot be used) by pipe connections in such manner that a circulation of hot-water out of and back to the hot waterstorage tank, or the hot water heater, takes place at least whenever the faucets are all of them closed. The inclusion in such a pipe circuit of appliances for filtering the hot water would ordinarily at least be impracticable; in view of the attendant resistance to flow.

Infaccordance with the present invention in what is considered its most advantageous form, where a hot water storage tank is used, an appropriate part at least of the water heating and hot water storing means is included in an endless pipe circuit (called heater circuit hereinafter) along with a chamber of. small cubic contents as compared with the storage tank and in the form of an at least approximately straight pipe;

while the pipe line on which the hot water faucets are located is included in another endless pipe' circuit (called pipe line circuit hereinafter) along with a chamber of comparatively small cubic contents and in the form of an at least approximately straight pipe; which latter chamber is arranged relatively to the former for transfer of heat between their respective liquid contents. The water heating and hot water storing means are connected with'the inlet of the filtering appliances by pipe connections which may either include a portion of,

or be wholly separate from, the said heater circuit. n ecte d at their outlet with the said pipe line circuit by appropriate pipe connections.

Thus the tendency of the hot-filtered water to cool off in the pipe line is counteracted .by the tendency to transfer heat from water in the heater circuit to that in the pipe line circuit.

Provision should be made for escape of air from each of the heat transferring chambersin order that collection of air therein may not check the flow through the chamber. Most advantageously the air passes .from 'one chamberto the filter, and from the other chamber to the pipe line circuit. This circuit would be vented through the faucets or through some other appropriate outlet or outlets.

Where a hot water storage tank is not used, only water heating-means, and not both.

water heating and hot water storing means, are available for inclusion in the heater circuit, as a whole or in an appropriate part; otherwise the apparatus in what is considered its best form is the same as where a storage tank is used.

Modifications by addition, omission or substitution can be made indefinitely as long as the substance is taken of any one or more of the hereinafter written claims. The accompanying drawings, which illustrate some of the forms which may be adopted, are, therefore, by way of example and do not exhibit all the modifications which would be within the scope of the invention.

Figure 1 is a partly diagrammatic viewof one form, mainly in elevation but partly broken away andin section.

Fig. 2 is a detail view.

Figs. 3, 4, 5, 6, 7, 8, 9, 10 and 11 are less complete views of other forms.

The filtering appliances are contoo - connected Parts not shown in Figs. 3 to 11 and necessary to completethe view can be supplied from Fig. 1 in each case.

Referring to Fig. 1, the water from the street main (or other appropriate source) is heating or other agency. Assuming for the 7 present that the plpes w, w and 3 should be omitted (as they may be) or should beclosed by valves, the hot water would flowto chamher. i by way of pipe connections g g and would return more or less lowered in temperature by way of the pipe connection Hot water flows to the filter 71 through connections composed of pipes g j and ap-. propriate passages in filter valve 70, to-- gether with the pipe Z; which last leads from valve is to the inlet end of the filtering appliances. The filter valve is and pipe Z may be like the correiponding .parts' in Patent 594,640, granted to the assignee of the aforesaid Joseph T. Manning. In filtering position the pipes Z are interconnected through the valve is.

n this position the outlet end of the filtering appliances is connected by pipe m with the pipe line a 'n'; on which hot water faucets p are located. The connection g allows air to escape from chamber f into the pipe j leading to the filter.

= aucets are shown on two vertical legs,

' and also on a horizontal portion of the pipe line; but they may be confined to one vertical leg or be otherwise placed as desired. They may be at such distance from the pipe line as may be desired; and the pi line can be carried back. and forth as db sired.

The ipe n as shown is connected by 'branc es n" with faucet branches p at oints near the faucets. This ipe n and its branches n" could bev omitted, if so pref ferred; and when it'is used all of pipe 'n above-the junctionsof pipe 7; therewith I could be" omitted. Any known or suitable system of pi line can, in fact, be used. vent v is s own, which can be opened to allow air to escape from the. pipe hne n n when desired.

The hot water from tank 6 is fiamd in heated conditionin filter i, and passes thence 1n heated condition through pipe line n n to such faucet or faucets 'pas may be open.

When the faucets are all. of them closed the water in the pipe line 10. circulates through the chamber g, which is'of small cubic contents as compared with storage tank 0 and in .the'form of a straight pipe,- 7

and which is included in an endless pipe ove'mber' 30, 1897 .dotted lines 51.

circuit with 'said pipe n n by means of appropriate plpe connections, which as shown include flanged unions r. her 4 the water isreheated by heat derived from the main heater 0 and transferred by the hot water of theheater circuit.

The

In cham- I chamber f as shown incloses chamber g and is'itself comparatively small in cubic contents and in the form of a straight pipe. At each end of chamber f is a'stufiing box t. Air can escape from chamber gthrough rigvltilhand union 7 to the pipe line 7:. n.

en one or more faucets p are open the hot water from filter 'i-may divide at the coupling to and flow part of it each way to the open faucet or'faucets; or provision can be made to cause a flow in one direction only, say by an upwardly closing check line without such protection.

Provision should be made for maintainmg filter i and ,other parts intermediate the heater circuit and the pipe line circuit, as, for example, by providing them with heat the temperature of the water in the retaining jackets, indicated by dotted lines 19. Heat retaining-jackets can also be provided such other parts, if any, as may be desired. Chamber 7 would ordinarily be provided with a jacket, as indicated by As thus far described, the main heater 7,- A

and storage tank '6 are both of them connected in circuit with the chamber f (heater circuit); since the water return ng by way of pipe in will naturally divide 1n the hottom of the tank I) and will rise in part I through main heater 0 and in (part through tank 6. If it should be desire for more of the so returnin water to pass through main heater 0, suita 1e disposition can be made, as, for example, by interconnecting the pipes h and e by means of the p 1g w. Conversely, ifit should desired to les- Ben the amount of returning water,"if any,

which should pass through the main heater.

Such pipe connectlons can be made more nearly or quite, separate from said heater circuit by connecting the chamber 7 with the tank Ii -by a pipe y with or without omitting connection gt. In Fig. 3 connection g is omitted; the w marked j"; and the chamber f in the heater provided with an air vent f.

In Fig. 4 is shown an arrangement for including a larger portion. of said heater circuit in the 1pc connections between tank and filter. oreover, the relative positions of the chambers in the heater circuit and the pipe line circuit are shown reversed inv this figure, chamber 7" being inside of chamber g, and the latter carrying stufling boxes t. A reducer 'l' r is shown at left hand end of chamber 7. Hot water from tank 6 passes by pipe g, chamber f and pipe 9" to filtervalve 70 (Fig. 1), and leaves chamber f by pipe 71. for return to tank Z) or heater 0.

In Fig. 5 the water from tank 6 passes by connection 6 to heater 0, and thence by pipe 2 to chamber f; from which it'returns to' tank 6 by way of pipe 3 ata point above the level'of connection 6. Pipe j" conveys the hot water to filter valve k (Fig. 1).

In Fig. 6 thechamber 9 (included in the pipe line circuit) is inclosed in the'hot be up or down, as preferred.

water storage tank Z), thus dispensing with a heat transferring chamber in addition to said storage tank and, of course, also with the corresponding pipe connections for in cluding such a chamber in circuit with an approprlate part ofthe water heating and hot water storing means. Notwithstanding the simplification in this direction, there are advantages, however, in the special heater circuit, exemplified in Figs. 1 to 5.

A. stufling box If the. apparatus of is shown in Fig. 6 at "the upper end of chamber 9", Where this latter passes through the T coupling 4,

attached by nipple and flanged collar 6 to the tank 5. The pipe connection j leads to. the-filter valve (Fig. 1)

in Fig. 7 the chamber 9 in. the pipe line circuit is formed on top of tion 26 in a tank which includes both chambers. The convex side of this partition may Stuifing boxes 27 are shown for the water inlet pipe a and the filter pipe j", which, passing through the reheating chamber 9", lead directly into and out of the storage chamber 2').

Where the main heater is a so-called instantaneous heater using gas as fuel, or is otherwise of suflicient heating capacity to heat the water satisfactorily while flowing to an open faucet or faucets, it may be conbetween storage tank and filter is M the storage. chamber 5 by placing'a dish-shaped partisidered advisable to dispense with- .a hot water storage tank. One arrangement for such a caseis illustrated in Fig. 8; in which water from the street main or other source is supplied by pipe at to the pipe 7 through which the water returns from chamber f to the main heater 0. The hot water passes from main heater 0 by pipes g' chamber f, or by pipes g j to the filter walve is (Fig. 1). K

' In Fig. 9 chambers 9" 9*" connected in parallel branches of n' of the pipe line' circuit are shown located in a heater 0, which may be heated in any appropriate way,.as, for example, by gas flames frbm a burner 8 why steam in a coil 2801" byboth. One or other of the said chambers can be omitted; or both of them can be used. The pipe j'i leads from heater 0 to filter valve 2: (Fig. 1). The water from the street main or other source enters heater 0 through pipe a" Flanged unions are shown at r.

The horizontally placed storage tank 6" of Fig. 10 is supplied with water by pipe a and is arranged for heating either by steam in coil 29 inside said tank, or by any appropriate agency in an outside heater 0 located at a lower level and connected with tank I) by pipes e d, or by heating means in both forms. In places, for example, where steam is supplied part of the year only, the heater 0 using solid fuel or gas could bev utilized when the steam is not available. A thermostatic valve is indicated at 30 for checking the flow of steam into coil 29 from branch '31 of steam supply pipe 32 whenever the water in tank 6" shall reach-. a predetermined temperature. A trap for discharging water of condensation is indicated at 33 in the outlet pipe 34 from 103 ,coil 29. The pipe j" leads from tank 6" to the filter valve k (Fig. 1).

The reheating chamber 7 is connected in circuit with tank I)" by pipes 35 and 36. Said chamber surrounds not only the ClHLII O- ber g, forming part ofthe pipe line circuit, but also a heater pipe 37 for supplementlng or replacing the water circulation in the circuit b, 35, 7, 36. Said heater pipe'37 is shown provided with steam connections 38 39, the former leading from the steam supply pipe 32 and the latter leading to the pipe 34, and also with connections 40, 41 for including said pipe 37 in circuit with the heater 0. In the connection 38 a thermostatic valve is indicated at 42 for checking the flow of steam into heater pipe 37v Whenever the water in chamber 43, which is included in the pipe line circuit, reaches a predetermined temperature.

It will, of course, be understood that thermostatic valves can be used wherever desired in any of the illustrated arrangements, or in any other arrangement.

In Fig. 11 the. water in the pipe line cirinsure 8,

cuit is reheated by the fiame of'a gas burner 15. The products of combustion therefrom are conducted over the chamber g by a casing 16; which is shown provided at its ends' with upright flues 17 and 18 draft downward through casing Each of the chambers g, g, g", g

in order to g. in the ipe line circuit isof comparachambers tively smal cubic contents and each of them, except chamber q" in Fig. 7, is in the form of an at least approximately straight pipe. Each of the chambers f, f, f in-the eater circuit is likewise of comparatively small cubic contents and in the form of an at least approximately straight pipe. Such site sides of the same heat conducting wall.

This is advantageous; as with equal area of conducting wall it gives a higher tempera ture to the water in said pipe circuit; but a transfer of heat could be effected between the two fluids while flowing in the same dlrection; and the transferjmoreover, could be indirect; as if two chambers, for example, were immersed in a conducting liqu1d,1n a casmg common to both; or -as If a circulatin liquid should absorb heat through the wall 0 one chamber from the liquid contents thereof and should impart it to the liiquid in the other chamber through the wall o the latter. .In- Fig. 10 the heating of water in chamber g would be effected by steam in heater pipe 37 indirectly through liquid in the chamber 7.

Byshifting the filter valve is (Fig. 1) the direction of flow of hot water through the filter can be reversed for washing the filterin material. 11 the washing position of va ve k the water passes from the top of filter to waste through pipe 20. Between the pipes and m is a valved by-pass 21 for temporari y allowing hot water (when so desired) to pass from the former to the latter pipe without passing through either the filteror a filter valve. Valves can be used I wherever desired. The reference numerals 22i1idicate each ofthem a valve; but all the valves shown arenot marked.

In some of the hereinafter written claims recital is made of water heating and hot water storing means and in others of water heating means. The ;omission to recite hot water storing means these latter have a good area of conducting .wall in proportion to cubic contents; and

claims is intended to make them more in- 5 P elusive. They thus are intended to cover apparatus which comprises water heatin means and other elements reclted in san claims respectively, whether such apparatus 7 0 should or should not embody hot water storing means also.

In like mannerthe recital of pipe connections whereby water from sald water heating means is conveyed to the filter inlet is applicable to connections for conveying the hot water thereto, directly or indirectl with or without intermediate 'passage o the same through hot water storing means.
